Sarcoma-virus-related RNA sequences in normal rat cells.
A rat type C virus spontaneously activated from the NRK (normal rat kidney) cell line was found to have two major size classes of viral RNA subunits sedimenting at 35 and 30 S. Virus-producing cells contained both RNA species, while normal "virus-free" rat cells contained primarily virus-specific 30S RNA species. A DNA transcript, specific for Kirsten sarcoma virus, prepared from virus activate...
متن کاملHarvey sarcoma virus: a second murine type C sarcoma virus with rat genetic information.
The nucleic acid sequences found in the Harvey strain of murine sarcoma virus have been analyzed by RNA.[(3)H]DNA and [(3)H]RNA.DNA hybridization techniques. The Harvey strain of murine sarcoma virus has been found to possess at least two sets of nucleic acid sequences. One set of sequences is contained in the Moloney strain of mouse type-C virus, and the other set is contained in DNA transcrip...
متن کاملLevels of rat cellular RNA homologous to either Kirsten sarcoma virus or rat type-C virus in cell lines derived from Osborne-Mendel rats.
DNA transcripts from V-NRK and RT21c rat type-C viruses were found to differ in their sequence homology to Kirsten and Harvey sarcoma viruses. V-NRK DNA transcripts consistently had homology to Kirsten and Harvey sarcoma virus, whereas RT21c DNA transcripts did not. To explain the differences, the nucleic acids and structural proteins of the two type-C viruses, released from each of two cell li...
متن کاملMolecular cloning, genomic analysis, and biological properties of rat leukemia virus and the onc sequences of Rasheed rat sarcoma virus.
Rasheed rat sarcoma virus (RaSV) has been shown to code for a protein of 29,000 Mr not present in replication-competent rat type C helper virus (RaLV)-infected cells. This protein is a fused gene product consisting of a portion of the RaLV p15 gag protein and the transformation-specific 21,000 Mr (p21) ras protein, which is also found in Harvey murine sarcoma virus. We now report the molecular ...
متن کاملSeparation of sarcoma virus-specific and leukemia virus-specific genetic sequences of Moloney sarcoma virus.
We have studied the nucleic acid sequences in nonproducer cells transformed by Moloney sarcoma virus or Abelson leukemia virus (two types of replication-defective, RNA-containing, viruses isolated by passage of Moloney leukemia virus in BALB/c mice). DNA probes from the Moloney leukemia in virus detect RNA in both Abelson virus-transformed nonproducer cells and Moloney sarcoma virus-transformed...
